Nested Loop Example in Velato — Velato Code
Shows nested loops with MIDI note sequences representing inner and outer loops.
[MIDI-BASED] Notes: C4 -> outer loop start, D4 -> inner loop start, E4 -> increment, F4 -> check inner, G4 -> jump inner start, H4 -> check outer, I4 -> jump outer start, J4 -> output. Stored in a .mid file.Velato Language Guide
Velato is a Rust library (crate) that parses and renders Vello-compatible graphics from Lottie JSON animation files, enabling vector animations in Rust applications.
Primary Use Cases
- ▸Rendering Lottie animations in Rust desktop or cross‑platform apps
- ▸Embedding vector-based animations in Rust game UIs
- ▸Interactive UI animations for Rust GUI applications
- ▸Converting Lottie projects to native Rust-based rendering pipelines
- ▸Prototyping or experimenting with animated graphics in Rust + Vello
Notable Features
- ▸Parse full Lottie JSON into Rust structures
- ▸Render using Vello’s GPU-accelerated graphics backend
- ▸Support for rendering to desktop (with winit) and Web (via wasm + WebGPU when available)
- ▸Dual-license (Apache-2.0 OR MIT), friendly for open‑source and commercial use. :contentReference[oaicite:5]{index=5}
- ▸Integration with Vello scene graph APIs for further drawing or layering
Origin & Creator
Velato is an open‑source Rust crate maintained by the community; its repository shows incremental releases (e.g. version 0.6.0 in May 2025) targeting Lottie compatibility. :contentReference[oaicite:4]{index=4}
Industrial Note
Velato is used by Rust developers who need to integrate high-quality vector animations (from Lottie) into Rust applications or games - especially those built on Vello - without relying on JavaScript or external runtime, giving full control and performance in a system-level language.
